I was thinking of buying a Yamama 1200 or Denon 2802 which both have prologic II and DTSES. I was just thinking, would it be ok for me to buy a 3801 even though it does not have prologic II, it has Neo 6, which is from what I understand is similar to prologic two, better to get the 3801 or 1200/2802? Also, the 2802 does not have Denon's DDSC. The 2801 and 3801/3801 have it. What does it do, and what will the benefits be, and will I be able to notice them?
